ASTM-F describes the standard test method for Detecting Seal Leaks in Porous Medical Packaging by Dye Penetration. The current test method is ASTM F dye penetration. • It has been used for many years for testing seal integrity of sterile barrier systems. • Round robin. While the traditional ASTM F Dye. Penetration standard is Triton-X used in dye penetration testing is a non-ionic surfactant with both a hydrophilic.

However, since ASTM F testing is designed solely to detect leakage, components that illustrate any indication of leakage are usually rejected. The Creep Test provides a test for slow shear of the adhesive bond similar to a dead weight hanging on the seal.

Overview of ASTM F Dye Penetration Integrity Test

The dye will have discolored the surface of the material. A dye penetrant solution is applied locally to the seal edge to be tested for leaks. However, since these tests are designed to astn leaks, components that exhibit any indication of leakage are normally rejected. Observe the package for any leaks originating from the inside edge of the package seal towards the outside edge of the package seal.

These leaks are frequently found at seals between package components of the same penetratin dissimilar materials. The Eyedropper method requires the packages to have an unsealed area that extends beyond the outer edge of the seal.

The dye will have discolored the surface of the material. For more information visit www.

Because air escapes through the walls of a porous package during inflation, the flow rate must be increased to compensate for the lost air through the walls and create the back pressure in the tesg package. Place a bead of solution between the two materials along the outer edge of the package seal, ensuring the entire outer edge of the seal is wetted with the dye solution.


This pressure creates the force needed to rupture the seal. Requirements ASTM F testing is limited to porous materials which can retain the dye penetrant solution and prevent it from discoloring the entire seal for a minimum of 20 seconds. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

The package will be visually inspected for dye penetration after contact with the dye penetrant astmm a specified time. As a guide, each Test Method above recommends observing each seal for a maximum of 5 seconds on a 4-sided package 20 seconds total. Uncoated papers are especially susceptible to leakage and must be evaluated carefully for use with each test method.

There is no general consensus regarding the level of leakage that is likely to be detrimental to a particular package. Packaging must be free of condensation or any other source of liquid water. The test methods are limited to porous materials which can retain the dye penetrant solution and prevent it from discoloring the seal area for a minimum of 5 seconds. Harmful biological or particulate contaminants may enter the device through leaks. No indication of leak size can be inferred from these tests.

In the Burst Testair is introduced into the package at a predetermined pressure and flow rate. The porosity or lack thereof of the package material determines the inflation rate for the burst test. Historical Version s – view previous versions of standard. After contact with the dye penetrant for a specified time, the package is visually inspected for dye penetration. Either is to be regarded as standard. Water already in the seal defects may render them undetectable with a dye penetrant.

The presence of a number of small leaks, as found in porous packaging material, which could be detected by other techniques, will not be indicated. Please keep this in mind when developing your studies and validations. They are not quantitative.


Here is a quick overview of the changes: Leaks may also result from a microscopic pinhole in the packaging material that is invisible to the human eye. If wicking does occur, it may be verified by observing the porous side of the subject seal area. Observe each seal for a recommended duration of 5 to 20 seconds.

Link to Active This link will always route to the current Active version of the standard. If wicking does transpire, it may be verified by observing the porous side of the subject seal area.

ASTM-F – Medical Package Testing

Refer to Appendix X1 for details on wicking and guidance on the observance of penetrattion positives. Leaks may also result from a pinhole in the packaging material.

ASTM F procedure requires that the dye penetrant have good contrast to the opaque packaging material. Along the extended unsealed area beyond outer seal edgethe transparent material is separated from the porous material with use of a finger, paperclip, etc. The dye solution used in penetration testing will wick through any porous material over time, but normally not within the suggested maximum time.

These leaks are frequently discovered at seals between package components of ddye same or dissimilar materials. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of penetratoon limitations prior to use.
